The black hole merger event GW150914 within a modified theory of general relativity

In 2016 February the first observation of gravitational waves were reported. The source of this event, denoted as GW150914, was identified as the merger of two black holes with about 30 solar masses each, at a distance of approximately 400 Mpc. These data were deduced using the theory of general relativity. Since 2009 a modified theory was proposed which adds near massive objects phenomenologically the contribution of a dark energy, whose origin are vacuum fluctuations. The dark energy accumulates towards smaller distances, reducing effectively the gravitational constant. In this contribution we show that as a consequence the deduces chirping mass and the luminosity distance are larger. This result suggests that the black hole merger corresponds to two massive black holes near the centre of primordial galaxies at large luminosity distance, i.e. large redshifts.
